Give bots tools and MCP servers per bot and workspace, with status and tests

- Bots and workspaces get tools and MCP servers from their settings
  pages; bots also from chips under the chat composer, removable there
- "Every bot" now gives one to every bot now and every new bot; each can
  still drop it (attach-every-bot-extensions.ts moves old installs over)
- Status lines: MCP servers record whether they connect, tools whether
  their last run worked
- Test connection in the MCP form and a Test panel in the tool form check
  the form as it is, without saving
- Hide Google sign-in on the login form
